PVC6Q254A01B00 Equivalent & Substitute Parts

Part Overview

The PVC6Q254A01B00 is a 250 kOhms, 0.5W through-hole trimmer potentiometer manufactured by Bourns Inc. with ceramic resistive material, side adjustment, and PC pin termination. This part is classified as obsolete, making identification of suitable substitutes necessary for ongoing design support and production continuity. The primary driver for substitution is the discontinued product status combined with the availability of functionally equivalent active alternatives.

Key Parameters

Substitute Part Grouping Explanation

The 3362M-1-254LF qualifies as a direct substitute based on the following critical parameters:

• Resistance value: 250 kOhms (identical)
• Power rating: 0.5W, 1/2W (identical)
• Tolerance: ±10% (identical)
• Temperature coefficient: ±100ppm/°C (identical)
• Number of turns: 1.0 Turn (identical)
• Adjustment type: Side Adjustment (identical)
• Mounting type: Through Hole (identical)
• Termination style: PC Pins (identical)

The primary difference is the resistive material composition (Cermet vs. Ceramic) and physical dimensions. The 3362M-1-254LF uses Cermet material, which provides improved stability and reliability characteristics while maintaining electrical equivalence within the specified tolerance and temperature coefficient ranges.

Parameter Comparison

Engineering Selection Recommendations

The 3362M-1-254LF is the appropriate substitute for the obsolete PVC6Q254A01B00 based on the following factors:

• All critical electrical parameters (resistance, power rating, tolerance, temperature coefficient, adjustment characteristics) are identical
• The substitute maintains active product status with ongoing manufacturer support
• RoHS3 compliance of the 3362M-1-254LF provides regulatory advantage over the non-compliant PVC6Q254A01B00
• The smaller physical footprint (6.99mm x 6.60mm vs. 8.00mm x 6.90mm) may provide PCB layout benefits
• Cermet resistive material in the substitute offers enhanced stability compared to ceramic material
• PC pin termination and through-hole mounting are preserved, ensuring mechanical compatibility with existing PCB designs

Frequently Asked Questions (FAQ)

Q: Can the 3362M-1-254LF be used as a direct replacement for the PVC6Q254A01B00?

A: Yes. All electrical specifications including resistance, power rating, tolerance, temperature coefficient, and adjustment type are identical. The substitute maintains the same PC pin termination and through-hole mounting configuration.

Q: What is the difference between Ceramic and Cermet resistive materials in these trimmers?

A: Both materials meet the specified electrical parameters (±10% tolerance, ±100ppm/°C temperature coefficient). Cermet material in the 3362M-1-254LF provides improved long-term stability and reliability characteristics.

Q: Will the smaller dimensions of the 3362M-1-254LF affect PCB compatibility?

A: The 3362M-1-254LF has a smaller face dimension (6.99mm x 6.60mm vs. 8.00mm x 6.90mm). Verify that your PCB layout accommodates the reduced footprint. The PC pin spacing and through-hole mounting remain compatible with standard PCB designs.

Q: What is the significance of the RoHS3 compliance difference?

A: The 3362M-1-254LF is RoHS3 compliant, while the PVC6Q254A01B00 is non-compliant. For applications subject to RoHS regulations or customer requirements, the substitute provides regulatory compliance.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts meet identical electrical specifications within the stated tolerance and temperature coefficient ranges. The functional performance in circuit applications is equivalent.
